The average person in the countries listed below puts more demand on the global ecosystem than any other, giving these countries the world's largest per-capita "ecological footprint", WWF data shows.

Here is the top 5 most polluting countries on Earth:

1. Qatar
2. UAE
3. Kuwait
4. Bahrain
5. USA

Of course Bahrain's population is small compared to all the other countries on the list, so the total contribution is relatively little. Still, let's hope Bahrain will drop off the top 10 list soon. Every one of us can do something to help it.
